I know this an old thread, but I had exactly this problem and, as this was the only discussion I found anywhere online, I thought I’d share a solution…
The Lewmar Wavegrip 16st winches were discontinued in the early 1990s. The strippers are impossible to source and Lewmar charge around £200 to recreate them.
However all is not lost!
The strippers for the newer Lewmar 16st Ocean Winch (available for around £10 on Ebay etc) can be easily adapted. Their diameter fits perfectly however they are too tall and the spacer doesn’t reach the chrome feeder arm.
It’s a simple task to file the height down – I used a sander attached to my drill, it took a few moments. Then you simply need to find/order a firm piece of plastic a couple of mm thick. Cut a section out that you can superglue/epoxy to the top of your Ocean stripper and ensure that it will reach the groove in the chrome feeder arm. This doesn’t have to be hugely precise – it just needs to ensure the stripper stays put while the winch rotates. In a sense you’re actually improving the stripper as you’re making even less space for rope to get jammed. Obviously, check it thoroughly. You can easily remove the necessary top sections of the winch and take them home to do this on your kitchen table.
Well done. You just saved £200.
